Such lines are known as fracture and are used to identify the gemstones in their initial stages of production when they are in the form of rough minerals. Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Oligoclase is Gems, Gems, Sixth Edition (2006), Sixth Edition (2006) and Uneven.
